Thank you, John, for your reply!
I already have a program that monitors the creation and close of files
in a specific directory.
I want to read the message from a pipe between the GUI and the monitor
program and
based on the output, change the color of the window (light). Therefore,
after it is initially
displayed in yellow, it can be changed to different colors.
I understand how to make it change based on a button click. I guess
that this is more how to connect
outside logic to the GUI that I have written. I just don't quite
understand.

Are you wanting it to change color when you click on
it? Or do you have a button? Or a timeout?
If you want it to change on click do something like...
Example::Example()
{
m_Color_Red.set_rgb_p(0.99, 0.00, 0.00);
m_Color_Yellow.set_rgb_p(0.99,
0.99, 0.00);
m_Color_Green.set_rgb_p(0.00, 0.99, 0.00);
m_Color_Black.set_rgb_p(0.00, 0.00, 0.00);
add(mc_HBox);
mc_HBox.pack_start(mc_VBox, Gtk::PACK_SHRINK, 0);
m_Light1.modify_bg(Gtk::STATE_NORMAL, m_Color_Yellow);
m_Light1.set_size_request(400, 300);
m_Light1.signal_button_release_event().connect(sigc::mem_fun(*this,&Example::onClickMLight1));
mc_HBox.add(m_Light1);
show_all_children();
}
void Example::onClickMLight1 () {
m_Light1.modify_bg(Gtk::STATE_NORMAL, m_Color_Green);
}
Does that help any?
